Psychics were recruited by the Ministry of Defence to locate Osama Bin Laden's secret lair, it was claimed yesterday.

Newly declassified documents revealed that the MoD conducted an experiment to see if volunteers could 'see' objects hidden inside an envelope.

It is claimed the ministry hoped positive results would allow it to use psychics to 'remotely view' Bin Laden's base and also to find weapons of mass destruction in Iraq.

However, after running up a bill of £18,000 of taxpayers' money, defence chiefs concluded there was 'little value' in using psychic powers in the defence of the nation and the research was taken no further.
